Application December 14, 1938, Serial No. 245,720 I 1 claim; (m me-41) IMy invention relates to barber chairs and the like, and has among itsobjects and advantages the provision of an improved head rest embodyinga vibrator unit. i 1

In the accompanying drawings Figure is a sectional view along theline5--5 ofll'igure 3; 1 h p 1 Figure 6 is a sectional view along the line6-6 of Figure 2; i

Figure '7 isa sectional view along the line l-A-I of Figure 6; and IFigure18 is a sectional view of the paper supporting roller. 1 1 In theembodiment selected to illustrate my invention, I make use of a headrest I0 provided with a conventional shank I2 which shank may beprovided with a series of openings so that the shank can be adjustedvertically on a chair (not shown) in the usual manner. Head rest I0includes end walls I4 recessed at I6 for housing the wall elements I8which are notched at to provide teeth 22 to certain of which I attachthe ends of coil springs 24 which support the usual pad 28. Wallelements I8 are inter-I connected into a unitary structure through themedium of cross bars 28 and 30, and each wall element I8 is hingedlyconnected with its re 1 spective wall I4 through the medium of a plate32 having a pivotal connection 34 with one end of the wall element.Thus, the wall elements I8 1 and the pad 26 are connected as a unitwhich may be swung from its full line position of Figure 1 to the dottedline illustrations therein to lend access to theroller 35 which carriesthe roll 38' of paper.

Figure 3 illustrates the paper as being pulled over the rounded edge 40of the pad 26, backwardly across the pad and downwardly across 1 theinner face of the bar 30 to be fixedly related thereto through themedium of a clamp flange 42 arranged for pivotal movement about its axes44 journaled in the side elements I8. Clamp flange 42 is provided withan arm 46having a finger grip 48 extending through an opening 50 in oneof the walls I4. Clamp flange 42 is normally held in the position ofFigure 3 through the medium of a tension spring 52. 1

I Figure 1 is a side elevational view of a head 1 Roller 36 isillustrated in FigureBpwhihroller includes a shaft 54 rotatablyjournaledat 56 in one of the walls I4. The other shaft 58 extends loosely throughan opening in the end I flange 60 and is provided with a body 62slidable 5 inside the tube 64 of the roller. Between the body 62 and astop 66 I interpose a compression spring 68 which urges the shaft 58 tothe which supports the head rest. T-head 80 in- 201 cludes a curvature82 which accommodates the paper roller 38 and is detachably connectedwith the head I8 through the medium of screws 84. Disc 14 is pivotallyconnected with the ears I6 through the medium of the shaft 86, and thedisc is provided with a plurality of openings 88 for selective receptionof a latch pin 90 which is slidably supported by a tube 92 anchored toone of the ears 16 by screws 94. Latch pin 00 is provided with a flange96 against which one end of a compression spring 98 bears for urging thelatch pin into the aligned opening 88. The opposite end of thecompression spring is arranged for abutting relation with the outer endof the tube 92. Thus the head rest I0 may be shifted to differentpositions about the shaft 86 as an axisand latched in such positions.

1 Head rest I0 is also adjustable about the horizontal head part I00 ofthe T-head 80. Figures Sand '7 illustrate the construction of the endsof the head part I00. Since both ends are constructed in the same mannerthe description of one will applyto both. Figure 6 illustrates one ofthe walls I4 as being provided with an offset I02 having a bore I04loosely receiving the short shaft I06 which also extends into the boreI08 in the head part I00. 1

Between the inner end of the shaft I06 and the end of the bore I08 Iinterpose a compression spring I I0 which normally urges the shaft I06to theposition of Figure 6. A transverse pin H2 is carried by the shaftI06, which pin is axially slidable in the slots H4 and projects beyondthe outer diameter of the head part I00 sufliciently far to be broughtinto selective reception in the notches H6 for latching the'wall I4against rotation about the shaft I 00 as an axis. Head part I00 isrounded at II8 to take the form of a shaft rotatably disposed in thebore I20 in the inner face of the wall I4. Thus circular wall I28 whichis secured thereto through the medium of screws I30.

Upon the bar I24 I mount an electromagnet I32 andbrackets I34 each ofwhich supports a vibrator head I35 which is mounted on a short post I36carried by the outer end of a strap I30 secured at I40 to the inner endof its respective bracket I34. Each bracket is provided with an armaturebar I 42 arranged in operative relation with the .pole I44 of theelectromagnet. Each vibrator head I34 is of the same construction.Figure 5 illustrates, the posts I35 as extending loosely throughopenings I46 in the semi-circular wall I20, while Figure 1 illustratesthe head rest I0 shifted to such a position as to bring the vibratorheads I34 into vibrating relation with the neck part I48 of the personbeing treated. Electromagnet I32 is connected with wires I50 and I52,one of which is connected with a con ventional' switch I54'and the otherconnected with a terminal I50'of the electric cord I58. A wire I isconnected with the switch I54 and the other terminal I52 connected withthe other wire in the cord I58. Closing of the switch 554 will energizethe electromagnet I32. Alternating current impulses excite theelectromagnet intermittently and cause the armature bars. M2 to beattracted thereto for imparting vibratory action tothe vibrator headsI34.

It will thus be seen that the head rest I0 may be utilized in the mannerof conventional head rests such as are employed in connection withbarber chairs, but the head rest maybe adjusted to the position ofFigure l for bringing the vi brator heads I34 into operating position.The head rest is additionally adjustable about the shaft I06 as an axiswhich permits a large range of adjustment of the head rest for operatingpurposes beyond the range of the adjustment about the shaft 86 as anaxis.

Cord I58 is connected with a detachable plug I64 so that the cord may bedetached when the head rest is not being used ,for massaging purposes.merit, the person being treated may take a reclining position in thechair with the head rest positioned according to Figure l. Vibratingheads I34 are so aranged in the head rest structure as to be completelyout of the way when the head rest is adjusted for bringing the pad 26 inthe usual head and neck supporting position.

I claim:

In a head rest of the type described, a support adapted to be pivoted todifferent positions about a horizontal'axis, a head supporting pad onsaid support, neck massaging means, electromagnetic means carried bysaid support, and means for operatively connecting said massaging meanswith said electromagnet, said support being adjustable to a position forsupporting a patients head on said pad with said massaging means locatedto massage the neck of the patient, and said support being adjustable toanother position for locating the head of the patient. on said pad butwith said massaging means out of range of the patients neck.
